Climate
change may be defined as the incessant day to day variation taking place in
the weather system throughout the world. The main factor behind the climate
change is human generated activities like increased consumption of fossil
fuel which in turn emits large amount of greenhouse gases like carbon dioxide
(CO2), methane (CH4), chlorofluorocarbons, and nitrous oxide thereby
resulting in global warming. The most extensive use among these is the increased
use of carbon dioxide which comes due to consumption of fossil fuels and
deforestation. With course of time rate of CO2 consumption and emission is
increasing at a much faster speed than expected. There are various other
factors contributing to climate
change which are plate tectonic movements, volcanic eruptions, orbital
variations, ocean-atmosphere variability. Climate Change 2019 will be a great event to discuss about the causes, impacts and
solutions to mitigate climate
change.
